Powershell脚本，用于使用CSV文件作为参数来查找和替换XML文件中的值

Question

I've created a Powershell script which generates an XML file. All the XML data is within the script and whatever items need to be repeated, I have them looped based on the amount of lines in the CSV (minus the header).

The next part of the script is where I'm having an issue. Based on the same CSV, I'm trying now to modify the generated XML file and do a find and replace. I generated which words need to be replaced from the loop such as FName1, FName2, FName3, LName1, LName2, LName3.

My problem here is that whenever I try to replace these words from the CSV file, nothing gets replaced unless I hard code FName1, FName2 and so on.

This is the code which I know is incorrect.... Basically I want it to look for any instance of FName(1,2,3 etc) and LName(1,2,3 etc) and replace it with $ _.FirstNames and $ _.LastNames.

$c = Import-Csv test.csv

Get-ChildItem test.xml | Foreach-Object {
  $xmldoc = (Get-Content test.xml | Out-String)
  $i = 0
  $c | Foreach-Object {
    $xmldoc = $xmldoc -replace 'FName' + $i++,$_.FirstNames `
    -replace 'LName' + $i,$_.LastNames
  }

  $xmldoc | Set-Content test.xml
}

This is a portion of the test.xml file

<ItemRef ItemID="FName1" Mandatory="No"/>
<ItemRef ItemID="FName2" Mandatory="No"/>
<ItemRef ItemID="FName3" Mandatory="No"/>
<ItemRef ItemID="LName1" Mandatory="No"/>
<ItemRef ItemID="LName2" Mandatory="No"/>
<ItemRef ItemID="LName3" Mandatory="No"/>

And this is the test.csv file:

FirstNames,LastNames
John,Doe
Jane,Doe
Mike,Smith
Samantha,Fox

Any help would be greatly appreciated!

Thanks,

Why are you incrementing your counter between FName and LName ?
Instead of using Get-Content to read in your file, use [IO.file]::ReadAllText() . [IO.file]::ReadAllText() won't break the file into an array based on line breaks.
